The Serpae Tetra, Hyphessobrycon eques or,Hyphessobrycon serpaeis a very attractive little fish. It comes from South America, from The
Amazon, Guaporé
and
Paraguay
Rivers.It has also been referred to as Hyphessobrycon
callistus.Other common names are the “Blood Characin”,
“Blood Tetra”, “Jewel Tetra”, “Red Minor Tetra” and the “Red Serpae”.The Serpae Tetra grows to about one and a
half inches long (3.8 cm).It can live
up to 7 years old.

Water Conditions

The Serpae Tetra is a tropical
fish and is unsuitable for unheated aquariums unless they are kept somewhere
that does not get cold.In the wild,
Serpae tetras live in soft acidic water, but they will adjust happily to the
conditions for a community aquarium with a temperature of24 degrees C (75 degrees F), with a neutral
pH and moderate hardness.

Food

Like many Tetras, the Serpae
Tetra is an easily fed omnivore.It
will eat any normal aquarium food, I suggest that it be fed a variety of food
in different form, including flakes, pellets, frozen food like Blood Worms, and
live food like wrigglers or daphnia when these are available.They are not big fish, and do not need a huge
amount of food, so a high quality fish food is well worth getting.

Companions

The Serpae Tetra has the
reputation of being a minor fin nipper.This slight tendency can be reduced by keeping them in as school of at
least six, and in a reasonable sized aquarium (I suggest at least two feet (60
cm) long.)In these conditions they will
not cause trouble to most fish, but I would not keep them with long finned and
slow moving fish like Siamese Fighting Fish, Guppies of Endlers Guppies.

Avoid large aggressive or
predatory fish with Serpae Tetras.As
with animals in general, try to keep some similarity in sizes of creatures
which are kept together.

Sexing

It is not easy to determine the
sex of Serpae tetras, but when in breeding condition, the female will be more
rounded.

Breeding

The Serpae Tetra is considered
to be one of the easier Tetras to breed.The fish should be conditioned beforehand with rich foods, preferably
including live foods.

The Breeding Tank should have
some plants including ones with fine leaves.The water should be soft and slightly acidic.

The parents will eat the eggs
and babies, so it is usual to remove them after spawning.The eggs should hatch in 24-28 hours.The fry can be fed on infusoria (protozoa),
fine commercial fry foods and hard boiled egg yolk suspended in water.Live foods will encourage growth of the
babies at all stages.

Pest Fish

Do not allow your pets to get
into an environment that they are not native to.
